It's a truly great camera. So underestimated.
It really is. I'm continually lost/amazed, almost "conspiracy theorist" about all those bad reviews - were they simply paid Canon insiders that wanted to push people to more expensive models? Like they owned the 70d-80d, were "experts / I know everything about everything" and then... dun dun d uuuuuuu n: Got the 90d and went from expert to Amoeba status? Maybe they got amnesia upon opening the box?!
Even Brian - on 'The Digital Picture' has clearly out of focus shots on his noise testing with the 90d. It took me a grand total of 15 seconds to dial in +2 for micro adjustment on my 100-400II. Done. Never looked back, never spent decades second guessing, I didn't need charts, I didn't have to get online and ask 552,000 questions, etc.... BOOM DONE movin on!
80d vs 90d:
90d vs R:
90d vs R5:
My personal fave as of late: The "R" ( $1599 on Amazon right now or somewhere else if you dislike Amazon for obvious reasons ) VS. the R5:
I picked ISO 6400 as - for Astro, that's about where you'd want to be - ISO 6400 F2.8 10-13 seconds at 15mm ( the "500 rule" in my opinion is far too deficient, so once you go longer than 15 seconds you have streaks instead of stars). Yes, the R5 is quantitatively "better" BUT - Is it $2300 "better" if you're doing boring/old fashion/slow moving landscape shots that will most likely NEVER be published by National Geographic, even though, everyone has this fantasy of getting that phone call: "We saw you're work, it's SO groundbreaking, we want to send you BILLIONS of dollars... NO, actually, we want to send you TRILLIONS of dollars!!..."
Back to the 90d:
I have been noticing this going on for a while now: Every "new" thing that comes out = "better" I really take the youtubers with a grain of salt, and really, they're just now after views/subscribers rather than accurate dissemination of information. My fave youtubers are the ones that will actually take a more skeptical approach.
It's like this: Do you need a 750hp Porsche to sit in stop/go traffic to go to Costco?
For me: The only reason I got the R5 was solely for the Astro work, and trips back to AZ for birds/horses. Otherwise, if one is not doing any of those activities/subject matters - the 90d is fine, or heck, you can pickup the "R" for $1599 right now, and gain some efficiency that way.. I like the idea of a cheaper camera that "annoys" the more expensive cameras.
I'm another happy 90D user. I use it mostly for macro and it is fantastic for that.
I love my 90D however I did buy the R7, having used it for a month now it is a 90D MARK II
What do I like about the 90D?
OVF - the optical viewfinder
status screen on top of camera
What don't I like?
inability to set multiple AF modes on the back buttons, the 7DII and 5DIV allows the AF-ON to be 45 point AF while "*" is set to single point
smaller than 5DIV and 7DII
What do I like about the R7?
The AF system!! Animal Eye AF, being able to set each button to different AF modes. I use the shutter button for full AF over the entire EVF the AF-ON to spot and the "*" to no AF It will get a birds eye or head at 100 yards, when I snap shoot as a bird suddenly appears it will lock onto the bird within limitations.
The new "wheel" for the F stops, fits my thumb well.
Dual SD Cards
15 FPS mechanical 15 or 30 electronic and ability to set a sound as quiet or loud as you want for the ES
control ring on RF lenses and on EF-RF adapter to control, for me I use it to change either ISO or the exposure value (+ or -)
Grip is deep enough to hold well
better ISO performance than the 90D - 6,400 even 12,800 can be used.
what don't I like
the height of the camera it is too small my pinky hangs below
so so battery life, I routinely get about 1000 shots before I must think about changing the battery (carry a spare)
EVF - not as nice as an optical view finder - but you can see you exposure before shooting or set it to simulated OVF
biggest nit was the height of the camera, too short but I solved that by creating a "battery" grip, basically a grip extension by taking a BG-E2 and cutting the part that goes into the camera off. Only downside is you have to remove it to change the battery slowing that down, but my typical pond side visit is about 2-3 hours and I have yet to kill a battery even with 1500 shots.
I am keeping my 90D but it is a backup at this time.
